Get a the source for a game that's pretty good and no one has. Edit
the source to make the calculator crash about 5 to 10% of the time,
and otherwise run the game.
Actually, there woould be a way to make a virus. Write something that
attaches to the front of other asm programs and causes the calc to
crash infrequently. Here's what it would have to do:
1) look through the VAT for asm programs and copy itself in front of
them
2)fix the checksum
3)crash the clac on about every 15th time.
then it would infect all the games and no one would really know(unless
they noticed hey, his tetris is 350 bytes bigger than mine).
